$db['default']['password'] = '123456';

$db['default']['dbdriver'] = 'pdo';
代码如上图
浏览器访问，出错
Fatal error: Uncaught exception 'PDOException' with message 'invalid data source name' in D:\ci\system\database\drivers\pdo\pdo_driver.php on line 114

pdo_mysql已经安装，没问题。gg 了一下
database.php里面的代码应该这样写
$db['default']['hostname'] = 'mysql:host=localhost';
$db['default']['username'] = 'root';
$db['default']['password'] = '123456';
$db['default']['database'] = 'mydb';
$db['default']['dbdriver'] = 'pdo';
